Imaging methods are used widely to understand structure of brain and other biological objects. However, sample penetration by light microscopy is limited due to light scattering by the tissue. A number of methods have been recently developed to solve this problem. In one approach (SeeDB) simple procedure for clarifying brain samples for imaging was(More)
Huntington’s disease (HD) is an autosomal-dominant inherited neurodegenerative disease resulting from expanded amino acid (CAG) repeat in the gene that encodes protein huntingtin (Htt). HD remains incurable for now. A lot of evidence implicates aberrant synaptic connection between cortical and striatal neurons, a key component of HD pathophysilogy, which(More)
Melanoma is a highly aggressive neoplastic disease attributed to transformed melanocytes. The efficacy of regimens of cytotoxic chemotherapy for advanced stage patients does not exceed 20%. Search for lymphocyte markers of patients' sensitivity to chemotherapy provides a rational basis for development of cytotoxic chemotherapy. Using blood lymphocytes we(More)
Huntington's disease (HD) is an inherited autosomal dominant neurodegenerative disorder caused by a polyQ expansion (>36 glutamine repeats) in Huntingtin (Htt) protein. It is believed that dysfunction of corticostriatal system is one of the main pathological events. Special attention is paid to synaptic dysfunction of transmission between cortical and(More)
Patients with advanced malignant melanoma have poor prognosis as conventional chemotherapy induces complete response in a very small fraction (not more than 20%). One of research strategies aimed at raising its efficiency is the search for markers predicting individual response to chemotherapy. Our study was concerned with evaluation of the potential of DNA(More)
Melanoma is among the most aggressive malignancies. Tumors with a thickness of 4 mm can produce metastases, and the mean survival of the patients is 9 months. The review presents modern classification of the melanoma types based on cytological and morphological indices (Clark model). Alterations of genes in melanomas are discussed in detail. These genes(More)
Melanoma is a highly aggressive tumor of melanocytes. The efficacy of different cytotoxic chemotherapy regimens does not exceed 20%. The search for markers for patient sensitivity to chemotherapy provides a rational basis for the development of cytotoxic chemotherapy. In this study, we evaluated six blood lymphocyte parameters (the efficacy of BER and MMR;(More)
Optogenetics is a modern nanobiological approaches allowing modulation of the physiological status of electrostimulated cells, including the neurons. The optogenetic approach was used to evaluate the efficiency of synaptic transmission between the neurons in a mixed corticostriatal culture. Synaptic contacts between the cortical and striatal neurons forming(More)
